Best generator for home backup

For home backup, the deciding specs are running watts, starting watts for the fridge, furnace or well pump, and a 120/240 V L14-30R outlet for a transfer switch or interlock. These are the models in this set that cover the typical essential-circuit list through a 30 A inlet.

Dual-fuel models let you store propane, which does not go stale like gasoline. CO-shutoff models are the safer pick.
